Hi there, @Jp131996. Welcome to the Fitbit Community Forums. I'm sorry to hear that your Inspire 3 is not tracking your SpO2 data. I will do my best to help you! 

Regarding SpO2, keep the following in mind to make sure your Fitbit device successfully measures your SpO2 values:

• Your device doesn’t retroactively measure your SpO2 values. After you install the clock face, you’ll see dashed lines until after your next sleep session.
• Charge your Fitbit device to make sure it’s able to collect data throughout your entire sleep session. Note that you may have to charge your Fitbit device more often when using the SpO2 Signature clock face.
• Your Fitbit device must sync with the Fitbit app before the clock face updates. Note that it may take around an hour for your SpO2 values to appear after you sync your device. For troubleshooting syncing, see Why won't my Fitbit device sync?

• Turning off any clock face permissions can cause the clock face to stop functioning. To check these settings:

  1. With your Fitbit device nearby, open the Fitbit app on your phone or tablet.
  2. In the Fitbit app, tap the Today tab > your profile picture > your device image.
  3. Tap Clock Faces.
  4. Tap the SpO2 Signature clock face.
  5. Tap Permissions. Turn on any permissions you turned off.
  6. Tap Details when you're done making changes.

• Your Fitbit device must be able to consistently track your SpO2 data:

  • Wear your device slightly higher on your wrist.

  • Make sure your device is in contact with your skin.

  • Your device should be snug but not constricting.

  • Tattooed skin can impact the accuracy of the red and infrared sensors on your Fitbit device.
